​​Census would like to inform everyone through this forum that we have updated the 2012 Economic Census - All Sectors: Economy-Wide Key Statistics (EWKS). It now has more summary levels and OPTAX is required. We recommend you make the necessary modifications in order to continue using this dataset without any problem.

If you have any questions or comment respond to this post or email dsd.ferrett@census.gov.

What is the difference between the Data Profile data and the Summary file data. It seems very similar, with some overlap, but also slightly different, and I don't understand the relationship between the two.
Is the Summary File information used to create the Data Profiles?
Are these two totally different surveys with different metrics?
It's not clear to me when I should use the Summary File vs Data Profile. I've leaned

Hi everyone,
I'm trying to calculate the daytime population at the block level and/or the block group level.
It's noted here (https://www.census.gov/hhes/commuting/data/calculations.html) that we can query the API and get the code "B08604 Total Workers for Workplace Geography."
However, this code returns the "null" value in various data sets (including ACS 5-year) at the block-group and block level.
It seems like

In order to get the proper titles for variables/cells in the data I needed to write a program to merge two Excel files. The two files are Sequence_Number_and_Table_Number_Lookup.xls and ACS2012_5-Year_TableShells.xls. The first one contains the sequence and line numbers so that I can get the values from the data-tables. The second one has indents in the cell titles so I know how to combine them to create a proper cell

I need a list of all the states' legislature's district names. I will use this list as the definitive list of district names that data is mapped to. I tried to use the " Census Name Lookup Tables" found here:
https://www.census.gov/geo/maps-data/data/nlt.html
but there are many district names that don't map properly to the district names returned by the 2012-5yr-ACS API. So, for example, if I submit the query:

Hi, I am attempting to examine households within a given geography, and would like to count the number of households which fill certain income and age constraints. For example:
Household contains person age 12
Household income between $50k and $60k
Is this possible using the ACS 3-year tables? When I load a generic tabulation, I know the fields exist (age, income, location) but I cannot get the conditional results (%

Census has added the very helpful restructured subject matter item lists (eg, http://api.census.gov/data/2000/sf3/variables.html). Thank you. I am seeking an easy way to search for two or more keywords (eg, Age, Hispanic) in a nonphrase structure that will highlight rows/items that meet that condition. ... by searching on the unmodified html. Any thoughts on this? Thank you.

I have a tool (geocoding, etc) that uses Census 2010 data and it puts out a report with '% Minority" and "Total Housing Units" -- how do I know what Census table originates this data ? And : What the corresponding table/field is in ACS ?

For ACS data - is there a way to tell which codes are valid for tracts vs block group?
Some codes work for both, some return "null" when the block-group level is queried.
For example, the following url works for the tract level:
http://api.census.gov/data/2010/acs5?key=4be82289939444f20513cd7c3c3eafb42e0d9ccf&get=B06007_003E,NAME&for=tract:*&in=state:08+county:059
But using the same code, it returns null for the

Hi,
Are there any commercial/free APIs that are available for developers to use that are ALREADY sourcing from the Census.gov datasets? Factual's Geopulse Context was doing so as recently as 2013 but they've deprecated their API. It generated easy to access and useful demographic data from a lat/long and made importing into chart libraries super easy.
Anyone know of anything similar? Happy to pay $ for a service that's
